I use a DLL where a function returns a `System.Single`. Its return value is `0.01`. Before pythonnet version 3.0 this got converted to a Python `float` also of value `0.01`. With Pythonnet 3.0 I get a Python `float` `0.009999999776482582` instead. I can reproduce this issue by creating `System.Single` objects.\r\n\r\n-   What commands did you run to trigger this issue? If you can provide a\r\n    [Minimal, Complete, and Verifiable example](http://stackoverflow.com/help/mcve)\r\n    this will help us understand the issue.\r\n\r\n    ```python\r\n    import clr\r\n    import System\r\n\r\n    # Parse a string to avoid conversion from Python float to dotnet\r\n    print(System.Single.Parse('1e-2'))\r\n    # Create a pure dotnet object without conversion back to Python (I think .ToString() gets called here?)\r\n    print(System.Single(0.01))\r\n    # Create a pure dotnet object without conversion back to Python and convert back to Python\r\n    print(System.Single(0.01).MemberwiseClone())\r\n    ```\r\n    ```\r\n    0.009999999776482582\r\n    0.01\r\n    0.009999999776482582\r\n    ```\r\n\r\n    With pythonnet 2.5.2 this will return\r\n    ```\r\n    0.01\r\n    0.01\r\n    0.01\r\n    ```\r\n","author":{"url":"https://github.com/m-rossi","@type":"Person","name":"m-rossi"},"datePublished":"2022-08-03T15:18:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/1896/pythonnet/issues/1896"}
